Portable AC Internal Resistance Tester (ACR@1KHz) for All Batteries 0-100V
Xtester-YR1035+20mΩ/200mΩ/2Ω/20Ω/200Ω,DC100V,high accuracy Battery Internal Resistance Tester DC Voltage Tester
INTRODUCTION
| MEWOI-YR1035+ battery internal resistance tester is a true four-wire internal resistance tester, which can measure the internal resistance and voltage at the same time. It can also be used to measure the resistance. The measurement results are displayed on the same screen. This product is suitable for battery configuration, battery performance testing, battery screening and other aspects.The machine structure exquisite, easy to carry, is your ideal electrician, electronic testing machine. |
SAFTY WARNING
The machine shall not input DC voltage greater than 100V. No AC voltage can be input under any conditions. MicroUSB port is used for charging and 4.5V-5.5V voltage is input.

Matters needing attention in the test
1. The machine has been calibrated before delivery, and there is no need to calibrate or reset the machine. |
2. After starting up, check the internal resistance and voltage range. For example, connect the test line to test directly on the automatic range AUTO. |
3. The twined test wire should not be disassembled, but should be wound in red and black when received, and should be wound in vain.Double stranded can enhance anti-interference and improve measurement accuracy. |
4. Each test line of the indicator pen shall be in good contact with the battery under test, and there shall be no connection between each test line. |
5. Use of Kelvin plus test wire: the clamp must be open when measuring the battery. There should be no direct contact between the two metal pieces of each clamp and the battery electrode. |
6. Use of 18650 battery stand: align the back edge of the movable stand with the length scale according to the length of the battery, and compress the negative contact with the battery before putting it in.So that the positive and negative poles can not expose the middle of the yellow needle, otherwise it can not be stable and accurate measurement. |
7. Use of probe test line: the positive and negative poles of the vertical battery press down the probe to shrink part of the probe and make both probes touch the battery independently.Make sure that the positive and negative surfaces of the battery are clean, otherwise poor contact can not be stable and accurate measurement. |
